HALT

HALT investigates a treatment option for advanced non-small cell lung cancer.

Disease site: Lung cancer

Treatment Modality:

Status: In follow-up

What is the study about? 

HALT investigates a treatment option for advanced non-small cell lung cancer. 

Non-small cell lung cancer is the most common type of lung cancer, affecting around 9 in 10 of people diagnosed. Some people with this type of cancer have certain genetic abnormalities, or mutations, in their cancer cells which can be treated with drugs called tyrosine kinase inhibitors (TKI). 

Tyrosine kinase inhibitors often work well to start with but then stop working as well because cancer cells build a resistance to them. This can lead to areas of cancer growing, or progressing, around the body. The HALT trial is looking at whether treating small areas of progression with a type of very precisely targeted radiotherapy called stereotactic body radiotherapy (SBRT) can help the tyrosine kinase inhibitor work better for longer.

The results of the HALT trial will be used to help decide if SBRT would be a helpful treatment for small areas of progression in people with this type of cancer in future.

 

Who is included in the study? 

HALT includes people with advanced non-small cell lung cancer (NSCLC) which has spread around their body. Everyone who joins HALT will already be receiving tyrosine kinase inhibitor (TKI) treatment and will have developed five or fewer small areas of cancer growth during TKI treatment. 

110 participants will join HALT from NHS hospitals and from European hospitals in the European Organisation for Research and Treatment of Cancer.

 

What are the study treatments? 

Participants will be in two treatment groups:
• Continuing to take a tyrosine kinase inhibitor
• Continuing to take a tyrosine kinase inhibitor plus as short course of stereotactic body radiotherapy 

Participants will have regular check ups during and after their treatment and we will collect information about how they are getting on until the study is completed.
